Google launches Gemini 3: Calls it the ‘World’s Best’ Model”

Google has officially launched Gemini 3, its newest and most advanced foundational AI model, with CEO Sundar Pichai immediately declaring it the "best model in the world for multimodal understanding." The launch signals Google's most aggressive move yet in the AI race, leveraging its entire infrastructure to challenge the dominance of rival platforms like ChatGPT.

Gemini 3 has already rolled out across the Google ecosystem, and is accessible to users through a new "AI Mode" toggle in Google Search, the Gemini app, and the Vertex AI developer platform.

Reasoning and multimodal mastery

Google DeepMind, the division responsible for developing the model, highlighted that Gemini 3 achieves a major leap forward, particularly in two key areas:

State-of-the-Art reasoning

Gemini 3 Pro is designed to move beyond simple summarization, tackling PhD-level reasoning on complex academic and analytical tests. Its responses are engineered to be more concise and insightful, offering "genuine insight" over generic platitudes.

An enhanced, cutting-edge version, Gemini 3 Deep Think, is also being previewed for safety testers for the most demanding, long-horizon problems.

Multimodal fluency

The model was built from the ground up to seamlessly synthesize information from text, images, audio, video, and code. This capability allows Gemini 3 to perform advanced tasks like:

Analyzing sports performance videos and generating coaching feedback

Translating handwritten family recipes across different languages

Generating dynamic, interactive visual layouts, such as a magazine-style travel itinerary, directly on the search page.

"Gemini 3 pushes the frontier of multimodal reasoning to help you learn in ways that make sense for you by combining its state-of-the-art reasoning, vision, and spatial understanding," said Demis Hassabis, CEO of Google DeepMind.

The full-stack advantage: scale and distribution

The most significant aspect of the Gemini 3 launch may be its distribution strategy. By owning the entire pipeline, from its own AI research (DeepMind) and custom chip hardware (TPUs) to cloud hosting and consumer-facing platforms, Google can deploy the model at a scale and speed rivals cannot match.

Unlike prior models that launched as standalone services, Gemini 3 is integrated into Google Search from the moment of release, making it instantly available to billions of users.

For developers, the model brings significant improvements in agentic coding, with Google launching Google Antigravity. This new agentic development platform allows the AI to plan, execute, and manage multi-step software development tasks across the terminal and browser.

The model is also well-suited for complex business use cases, from analyzing medical scans and production line video to automating legal and financial analysis with improved factual accuracy.

Analysts are calling the launch an aggressive pivot in the AI arms race, with one noting that the technical capabilities and integrated rollout of Gemini 3 directly pressures rivals who have been unable to match Google's full-stack approach.
